Hey guys I'm new to the forum and this is my first turbo car. It's a 1990 eagle talon tsi awd turbo. I picked it up today and when I was driving it home I noticed when I would hit boost it would go to 20psi and if I didn't let off it would fuel cut I think. It came with a turbo smart bov but I'm pretty sure it has no mbc. It's a stock turbo. There is also a "T" with some brass fittings and has a cylender that says turbonetics but there is no dial and the person who sold me it said it don't have a mbc. I'm very confused! The other mods on it are, cast header, 2.5" exhaust all the way, stage 3 clutch, oil pressure,air fuel, and boost gauges
